add a little baking soda to a drop of super glue to form a super-strength sealant. After quickly combining these two products with the help of a toothpick, immediately apply the mixture directly to the wall. After it dries, start sanding the hard, plastic-like finish until it’s flush with the wall. Not only is this fix effective for small holes, but it can solve cracks in corner walls too! One word of caution: Wear gloves and be sure that this super-strength, fast-drying glue never comes in contact with your skin. Otherwise, you may have an even bigger problem on your hands than a hole in the wall.
